1.1 Card reader to controller The cable connecting the card reader to the controller is recommended to use 8-core shielded twisted pair (3 cores are reserved). The wire diameter is greater than 0.3mm, and the distance from the controller to the reader must not exceed 100 meters. It is recommended to be within 80 meters.
1.2 Controller to Computer Controller Communication lines (including 485/422, 232, and Wiegand, etc.) must use the internationally accepted 8-core shielded twisted pair cable, which can effectively prevent and shield interference. Wire diameter greater than 0.3mm The bus length is not to exceed 1200. It is recommended to be within 1000 meters. If it is longer, please use other special 485/232 converters or repeaters, and choose a thicker communication cable. The controller GND485-485+ corresponds to the 485 converter GNDTD(A)TD(B) respectively. The communication line is connected in series, do not use star connection or local star connection (as shown in the figure).
If the line is too long and there are too many devices, add a terminating resistor (with jumper) to the last device. The bus can connect up to 128 controllers.
1.3 Three-way switch (control source) to controller The three-way switch to the controller must use a 2-core power cord. The distance from the controller to the three-way switch must not exceed 100 meters and the wire diameter should be greater than 1.0mm. More than 50 meters, with 2.0mm. (If the output 12V power supply has a significant voltage drop, you can fine tune the power supply voltage to 13.6V.
1.4 Routes require that their equipment lines not be strong or electric wire ducts. If it is limited by the environment, if you want to run parallel, you must keep away from more than 50CM.
2 Trips, Gate Controls Safety Notes
1. Although the controller already has anti-static and anti-lightning design, please make sure that the power supply and the chassis are well grounded to protect the circuit from static electricity, lightning, and other equipment.
2. Do not hot-swap wiring terminals, or electrified welding operation, the corresponding wiring socket should be unplugged before welding.
3, Do not disassemble the components on the controller, this may cause system information loss or chip damage.
4, connected to the +12V terminal, is conducive to give full play to the performance of the reader, if the reader is +24V power supply, please separate with a linear power supply, and the controller and common ground. Do not introduce +24V into the controller indirectly, otherwise it will cause burnout.
5, the controller can directly plug the UPS uninterruptible power supply to ensure that the system can continue to work after a power outage. The system is equipped with a power-off protection device, even if the power failure system setting information and records are not lost.
6. Try to avoid connecting the controller power supply and other high-current working devices to the same power supply. The operating current of the relay is a maximum of 7A. If you want to control a larger current device, install a more powerful relay. It is better to have a separately controlled switch from the main control power supply box.
7. When installing a remote controller or other additional value-added equipment, be careful not to introduce other electrical signals into the controller.
3 Trips and Barrier Controllers Installation
3.1 Card Reader Installation The installation height of the card reader is the normal hydropower installation standard (1.45 meters). All external equipment introduced into the device can not be pulled too long to avoid short circuit caused by exposure.
3.2 Controller Installation The controller is easy to maintain and safe when it is installed.
3.3 The isolator is installed in a concealed place and should not be touched.
